power source in accordance with applicable
electrical codes.
Do not touch electrode or internal compo-
nents without protection.
Disconnect power before servicing.
Do not remove the grounding lug in any elec-
trical plug.
Electrical shock can cause injury.
In case of maintenance inside the welder, make sure the
switch F is in “O” position and that the power supply
cable is disconnected from the main.
Periodically, also clean the inside of the welder and
remove any metal dust using compressed air.
HOW TO PROCEED AFTER MAKING REPAIRS
After making repairs, always ensure the wires are fully
insulated between the primary side and the secondary
side of the machine. Avoid the wires coming into contact
with moving parts or parts that heat up during operation.
Fit all the clamps back as on the original machine so as to
avoid any contact between the primary and secondary in
case of accidental lead breakage or disconnection.
Also t the screws back on with the toothed washers as
